Just found (via Google blog search, which I have fed into my feed reader) a nice review of the podcast version of City of Masks on Livejournal. The reviewer initially wasn't sold on my reading, until s/he (I think she) realized that I was "doing the voices" of the characters.
I don't have (and don't intend to get) a Livejournal account in order to comment directly on the post, but thanks, krazysidhe, for your kind words. I'm complimented that you thought of doing fanfiction, though I'm also glad you decided not to. And (if you find this), have a look at The Y People and see if you like that too.
